QUILL AND HOUSING FOB MOISTURE-EXTBACTORS FOR DRYIIIG- CLOTH ES.

To all whom it may concern:

Be it known that I, ISAAC F. WILLEY, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented anew and useful Quill and Housing for Moisture Extractorsfor Drying Clothes, of which the following is a specification.

My invention relates to a novel construction of quill and housingemployed in connection with motor driven extractors or clothes-dryingdevices of a character generally similar to that disclosed in LettersPatent, No. 1,252,214, granted to me January 1, 1918, in which thebasket is located at the upper portion of the machine and driven orrotated from underneath by means of an electric motor the armature ofwhich acts as a spindle for the basket, and the mo tor case of which is'hung at the top and as heretoforeconstructed free to vibrate to agreater extent than. desirable.

As heretofore constructed, machines of this character have possessedcertain disadvantages which it is an object of my invention, generallystated, to overcome by a simplification of parts and the elimination ofcertain of them which have been found unnecessary.

The special object of my present invention is to so mount the spindleand the, quill which it rotates, with reference to the cup within whichthey are both contained, and with reference also to the base withinwhich the cup is maintained, as to provide means which not only permitsrapid rotary movement of the spindle but also and at the same timeautomatically takes up the wear and maintains the rotary parts in avertical line, with a minimum of friction.

Further objects of my invention are' to provide means of an eflicientcharacter through which the motor-supporting devices are assembled withreference to each other, supported from the base, and controlled orstayed against such rocking or vibratory movement of the motor andbasket as are inseparable from machines of this character.

For the purpose of illustrating my invention, I have shown in theaccompanying drawin s a certain type and embodiment of it whic is atpresent preferred by me be- Specification of Letters Patent. Patented Ot. 22 1918. Application filed m 15, 1918. i

cause in practice it will give satisfactory and reliable results. a 1

It is to be understood, however,that the various instrumentalities inwhich my invention is shown as embodied can be Variously arranged andorganized, and that my invention is not therefore limited to the precisearrangement and organization of the instrumentalities which are typifiedin the construct1ons shown in the accompanying drawings and hereinafterdescribed.

The drawing represents in central, vertical, sectional elevation so muchof an extractor as it is necessary to illustrate, in connection with thedevices which my invention comprehends and in which it is embodied, apart only of the motor and of its housing being shown.

In the drawings. 1 designates the base of the machine, it being a fiatplate centrally apertured at 2, and having superposed upon it a hollow,cylindric, upstanding base-housing 3, which is formed with a radiallyoutwardly extending flange 4, adapted to be connected with the base uponwhich it rests by headed screws 5.

The hollow cylindric interior of this base-' housing 3 is internallyformed or provided with stepped circular ledges 6 and 7 for the purposeof receiving and supporting against downward movement outer andreversely correspondent ledges 8 and 9, of a stepped sleeve 10, ofrubber or equivalent cushioning material.

Internally this cushioning sleeve is formed with circular ledges 11 and12, and its top is flattened to form an additional ledge 13, upon whichrests an outwardly extending flange 13 on the cup, so as to support saidcup. I

14: is a cup which supports the base plate 15 of the motor housing 16.17 is any usual I an internal central ledge 23 upon which rests a hollowcircular supporting plate 24, which carries the central ball race of thequill.

25 is the quill' which surrounds and is connected with the motor spindle26. Thls spindle near its upper part is formed with? a-step 27 whichrests upon asleeve 28,- preferably packed within the base plate 15 ofthe motor housing 16.

The quill is formed with an upper overhanging ledge 29 and witha lowerledge 30, which respectively rest upon the upper c rcular bearing plate31 and the lower circular bearing plate 32,the lower bearing plate beingheld in place by a basal 'fiange 33 which is secured by bolts 34 to themotor spindle 26.

35 are a preferablv double set of upper ball bearings, which areconfined and travel in a raceway composed of an outer circular Iinternally chan ieled raceway plate 36 which concentrically surrounds aninner raceway plate 37 which rests upon a step 38 formed near the upperend of the quill.

39 are a set of central ball bearings which are confined between theplate 31 and a secondary plate 40 which rests upon the supporting plate24, the plates 31 and 40 together forming the raceway for aid balls.

41 are a preferably double set of lower ball bearings which are confinedand travelin a raceway composed of the inner lower ball bearing plate 32and an outer ball hearing plate 42, as clearly illustrated.

Obviously, the central set of balls and their ball races'constitute aroller bearing for the support of the quill and spindle as rotatingwithin the cup and resist end thrust,while the upper and lower ballswithin their respective ball races serve as roller bearings to resistthe radial thrust of the rocking of the cup and its contents.

Extending radially outward from the upper part of the base housing 3 isa lug 43 from which is erected the standards 44, encompassing which is atubular cushion 45 of rubber of other-preferred material which, in themounting of the device, is entered within an apertured ring 46 extendinglaterally from the cup 14. The function of this device is by itscushioning effect to resist any throw or rocking of thecup and itsioning material interposed between the basehousing and the lowerexteriorof the cu a quill, a motor spindle within said qui 1, an a plurality ofall-bearings between the quill and the cup and within the cup.

2. In a moisture extractor, the combination of, a central, apertured,supporting base, a cylindric, vertically extended internally steppedbase-housing erected from the base and encompassing the a rture of saidbase, a cup which supports t e motor housing and contains within it aquill and motor spmdle, and which is externall stepped, and a cylindriccushion interposed base housing and the cup and both externally'andinternallystepped in corres ndence with the steps of said cup an saidbase housing.

3. In a moisture extractor, the combination of, a central, apertured, suporting base, a cylindric, vertically exten ed basehousing centrallyerected u on said base, a cup the lower ortion of which extends withinthe base an to the up er portion of which is secured the 'motor materialinterposed between t e base-housing and the lower exterior of the on aquill, a motor spindle within said qui 1, a

between the ousin cushioning plurality of ball-bearings between thequill withm the base and to the upper portion of i which is secured themotor housm cushionmg material interposed between t e basehousing andthe lower exterior of the cup, a

quill, a motor spindle within said quill, and a cushioning deviceextending laterally outward from the base-housing and operative inconnection with the cup.

5. In a moisture extractor, the combinaation of, a central, apertured,supporting, base, a cylindric, vertically extended internally steppedbase-housing erected from the base and encompassing the aperture of saidbase, a cup which supports the motor housing and contains within it aquill and motor spindle, and which is externally stepped, a cylindriccushion interposed between the base-housing and the cup and bothexternally and internally stepped in corres ondence with the steps ofsaid cup an said base-housing, and a cushioning device extendinglaterally outward from the basehousing and operative in connection withthe cup.

6. In a moisture extractor, the combinaation of, a central, apertured,su porting,

base, a cylindric, vertically exten ed inter nally stepped base-housingerected from the base and encompassing the aperture of said base, a cupwhich supports the motor housing and contains within it a quill andmotor spindle, and which is externally stepped, a cylindric cushioninterposed between the base-housing and the cup and both externally andinternally stepped in correspondence with the steps of said cup and saidbase housing, a cushioning device extending lat- 10 era-11y outward fromthe base-housing and operative in connection with the cup, and aplurality of ball-bearings between the quill and the cup and within thecup.
